While not as easy to piece together as - say - figuring out Clark Kent is actually Superman, anyone who's determined enough, and searches hard enough, could surely surmise that Batman is billionaire Bruce Wayne.
Still, you want it to be a challenge for that person, right? They shouldn't just be able to stumble across the information, especially if they weren't even actively looking for it. But ever since Alfred escorted Vicki Vale into the Batcave back in 1989 because he thought she was Bruce's soulmate after one date, the Batman films have had some issues when it comes to keeping secrets. Even Nolan's Dark Knight trilogy had the Caped Crusader clueing in those close to him about his alter ego.
The latest incarnation of Batman - as seen in Batman v Superman: Dawn of Justice, Suicide Squad, and Justice League - has similar problems, though it feels a bit magnified given how many supers he currently surrounds himself with. Let's take a quick look at all the characters in the DCEU films who currently know that Bruce Wayne likes to moonlight as a crazed costumed vigilante...
That's a lot of folks, folks. It's not just Batman's teammates who know the truth, but also anyone who's powerful and nefarious and just wants to know a little bit more about a famous rich guy who's also mysteriously beefy. As usual, like in the comics, Bruce's roughhouse rooftop escapades are the worst kept secret in Gotham.
Did we miss anyone who knows Batman's ultimate secret? How about those fishing village folks? Or that rooftop burglar who's weirdly chummy with Bats? Put it in the comments!
